Question

insulin is an important hormone that allows the body to use glucose from food. after an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. the glucose causes the beta cells to release insulin. insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.

what does this information best demonstrate?

• cells interact with other cells for regulation and homeostasis.
• beta cells are not necessary for glucose to be utilized.
• a hormone is a protein that performs many functions in the body.
• only certain cells can use glucose to produce energy.

Explanation:

Analyze the provided text

The text describes how glucose triggers beta cells in the pancreas to release insulin. Insulin then travels through the bloodstream and binds to receptors on other cells, enabling them to take in glucose for energy. This is a classic example of Endocrine Regulation where cells communicate to maintain internal balance.

Evaluate the first option

The first option states: "Cells interact with other cells for regulation and homeostasis." This directly matches the description of pancreatic beta cells releasing a hormone (insulin) to signal other body cells to absorb glucose, regulating blood sugar levels.

Evaluate the second option

The second option states: "Beta cells are not necessary for glucose to be utilized." This contradicts the text, which explains that glucose causes beta cells to release insulin, which is required for other cells to take in glucose.

Evaluate the third option

The third option states: "A hormone is a protein that performs many functions in the body." While insulin is a peptide hormone, the text focuses on a specific pathway of cellular communication and regulation rather than defining the biochemical nature or diverse functions of all hormones.

Evaluate the fourth option

The fourth option states: "Only certain cells can use glucose to produce energy." The text mentions insulin attaches to receptors on "other cells" to allow them to use glucose, but the primary demonstration of the passage is the coordinated interaction and regulation process itself.

Answer:

• (A) Cells interact with other cells for regulation and homeostasis. (Correct answer)
• (B) Beta cells are not necessary for glucose to be utilized.
• (C) A hormone is a protein that performs many functions in the body.
• (D) Only certain cells can use glucose to produce energy.
